PRINTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 415,985, dated November 26, 1889.

Application filed May 20, 1889. Serial No. 311,438. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR L. STEVENS, a citizen of the United States, residing at Philadelphia, in the State of Pennsylvania, have 5 invented a new and useful Printing Device,

of which the following is a specification.

My invention relates to a device forprintinga brand or number upon paper bags, and is designed to be attached to a paper-bag machine and work simultaneously with it. It is designed more particularly to be used in connection with the paper-bag machine described by me in an application filed March 14,1889, Serial No. 303,232; but it is equally well adapted to other machines and for other purposes.

The object of my invention is to make a simple device that will comprise a type-roll and ink-fountain combined, that will insure equal distribution of the ink, that will admit of a quick change of type and an adjustable impression, that will protect the ink from the atmosphere, and that will be self-contained and accessible, all its internal movements being perform ed consequent upon the simple rotation of the fountain-roll. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal section through the roll. Fig. 2 is a transverse section on line F G. Fig. 3 is a transverse section on line D, and shows also the position and relation of the fountain-roll with other rolls in a bag-machine. Fig. 4 is a transverse section on lineA B, showing device for feeding ink. Fig. 5 is a detail view of one of the bearings and device for regulating the impression. Figs. 6 and 7 are views of theinkdistributing roll, and Fig. 8 is an illustra- 0 tion of the class of work the device is designed to do.

Similar reference-signs refer to similar parts throughout the several views.

The fountain-roll 1 is made in two parts, and secured together by screw-bolts 2 and keyed to shaft 6. The shaft 6 is supported in bearings 7 and 8, and has keyed to its end the disk 9. The disk 9 has a T-groove 10 in its face. The driving-gear 11 is clamped to the face of the disk by the bolt 12 in the T- groove. The end of the shaft is squared at 13. The cored chamber 3 in the roll 1 is for ink. At the center of the roll its diameter is reduced at little, forming an ink-distributing surface at. A hole is drilled from the end in such a position that it will cut through or be tangent with the surface 4, and has inserted in it the spindle 5. The metal-is cut away a little at 14, leaving the top of spindle 5 exposed. IIoles 42 are drilled through from the spindle-chamber into the ink-chamber 3, from which the ink flows by centrifugal action due to the rotation of the roll. The spindle 5 thus forms a valve which closes the passage for ink,but feeds it slowly, as used, by oscillatingin its seat. This is accomplished by means of the fork 17, secured to the outer end of the spindle and spanning the fixed eccentric 16, which is formed on the end of the bearing 7. The ink is distributed over the surface 4 by means of the roll 15. In the opposite side of the fountainroll from the spindle 5 is the sliding type-block 18. On the end of bearing 8 is the adjustable sliding block 19, having a sleeve-extension terminating in an eccentric 20. One side of the sliding block 19 is dovetailed with the bearing 8, and in the other side is inserted the screw 21, the blocklt) being threaded and counterbored a short distance in at each side to allow the heads of the screw to enter. The half of the hole for screw 21 that is in the bearing 8 is smooth without threads, and the heads of the screw bear against each side. By turning the screw the block 19 is caused to slide across the end of the bearing 8, increasing or diminishing the eccentricity of the collar 20 with the shaft 6.

Fulcrumed on pin 22 in roll 1 is the fork or yoke 23,which spans the eccentric 20. On one arm of the fork is the boss 24, which is drilled out to receive the shouldered pin 25. A slot or opening is made through the web of the roll 1 into the radial slot containing the type-block, and through this opening extends 9 5 the boss 24 and pin 25. The type-block is slotted to receive the pin which holds it in po- 1 The pin 25 has a nut or head 26 and sition.

. the hinged piece cured to the frame of the machine by means The roll is forced upward a spring 27 forces the pin into the slot in the type. The type can be removed by'pulling back the pin by means of the head 26. As the roll 1 revolves, the fork 23 will, by means of the eccentric 20, vibrate the pin 25 toward and from the center of the roll, thus alternately depressing the face of the type evenwith the depressed surface i when the type is opposite the inking-roll 15, as in Fig. 3, and raising it even with the outer surface when revolved to the opposite side or to the point where it is desired to impress the type against the paper.

Fig. 3 shows the relative position of the fountain-roll with other parts of a bag-machine in which the roll 28 is the impressionroll, or the roll against which the type is pressed, and has in this case a yielding surface at 29, Where the impression is received. The bags are formed and delivered from between the rolls 28 and 30 and pass between 'rolls 2'8 and 1. Near the upper end of each bag is generally a 'bra nd'or number denoting its sizeyas in 8. are geared together and make'on'e revolution for each bag. To time the roll 1 so that the type Wiil print at the desired place 'on the bag'the screw 12 is loosened, and as the bag is brought to the desired position the roll 1 is turned by ineans'o'f the square head 13 so that the type will impress the desired :place on bag. The bolt 12 is then tigh tened,clampingthe #gear to shaft, and as the gear 11 meshes with 'aco'rresponding gear on roll 28, it follows th'at'tlre relative position of the rolls 1 and '28 remain iixed until it is -desired to change them again by the means just described. The bearings for the roll 1 "are supportednpon stiff steel springs 31, bol'tedto the frame of the machine, the object being to insure firm contact between the surface of the rolls 1 and 28, at the-same ti me'al'lovving varyin g thicknesses of paper to pass between them. The ink distributin roll 15 is carried'on one en'dof the spindle 32, which has hearings in This hinged piece is seof the foot 34.

the type and ink-fountain by means of the spring 35. The spindle 32 is s-plined and has -'a Worm 36 thereon. Engaging with this Worm is the worm-wheel 37, secured to a stud '38, having an eccentric head 39. Fulcruined to the hinged piece 33 is the forked ink and the type set to register at the right point on the bag, and the machine started. The fountain-roll revolves-once for each bag, and as the type approaches the roll 28 the fork a3, in revolving around the adjustable These rolls 1, 2S, and 30 eccentric collar 20, forces the type out against the roll 28 with a pressure depending upon the ad j ustment of said eccentric by means of the thumb-screw 21. As the motion of the roll continues the type is Withdrawn and brought even with the ink-distributing sur face 4, and in this position passes the roll 15. At each revolution of the fountain the spin- .dle 5 is oscillated by means'of the fork 17 and eccentric 16, thus supplying ink to the roll 15. The roll 15 revolves by contact with the fountain-roll and has a lateral movement, as before described, for the purpose of distributing the ink uniformly.

All the movements required to perform the 4 various functions and offices of the parts are secured by simple means, dependent upon the rotation of the roll 1, and the device is -all self-coi'iiained, thus making it well adapted to be attached to any machine.

Having described my invention, what I claim as new, and-desire to secure by Letters Patent, -is' I 1. in a printing device, the combination of an ink-fountain roll with'a sl-idingtype-bl'ock,
